<asp:Repeater id="parentRepeater" runat="server">
<itemtemplate>
  <b>
   <%# DataBinder.Eval(Container.DataItem, "au_id") %>
  </b>
  <br>
  <asp:repeater id="childRepeater" runat="server"
                    datasource='<%# ((DataRowView)Container.DataItem)
      .Row.GetChildRows("myrelation") %>' >
   <itemtemplate>
    <%# DataBinder.Eval(Container.DataItem, "[\"title_id\"]")%><br>
   </itemtemplate>
  </asp:Repeater>
</itemtemplate>
</asp:Repeater>

6. Add the following page directive to the top of the page:
7. <%@ Import Namespace="System.Data" %>

8. In the code-behind page, replace the following line in the Page_Load event
9. //Insert code in step 4 of the next section here.

with the following code:
         //Create a second DataAdapter for the Titles table.
         SqlDataAdapter cmd2 = new SqlDataAdapter("select * from titleauthor",cnn);
         cmd2.Fill(ds,"titles");

         //Create the relation between the Authors and Titles tables.
         ds.Relations.Add("myrelation",
         ds.Tables["authors"].Columns["au_id"],
         ds.Tables["titles"].Columns["au_id"]);

This adds the Titles table to the DataSet, and then adds the relationships between the Authors and Titles tables.
10. Save and compile the application.
11. View the page in the browser, and then verify that the page works so far. The output should appear as follows:
